Logging a day
One tap is enough on an ordinary day; everything else is optional. This guide walks a single day's entry — what each part is for, and how to change or remove it later.
One day at a time
How to log a period
Open a day, record bleeding, and the app does the rest. One tap on today is enough to start.
Each day holds one entry: flow level, tracked options, and an optional note. Logging bleeding on a day marks it as a bleeding day; consecutive bleeding days form a period.
The quick-log action on the overview records today in one tap. The calendar opens any day — past days can be filled in later, so a forgotten day is never lost.
Everything works offline. Entries sync to the account’s other devices the next time the device is online and signed in.

Starting a day
When a period starts, logging it is one tap: the overview offers Period started today. That records the day, marks it as bleeding, and starts a new cycle count — history and estimates update from that single tap.
Days do not have to be logged the day they happen: the calendar opens any past day, so a forgotten day can be filled in later, and logging a few periods start-to-finish is what keeps the estimates sharp.
One thing the app will ask about: starting to log bleeding much earlier than expected opens a confirmation — Start a new cycle? — because logging flow starts a new cycle, while spotting never does. It is a checkpoint, not a scolding; either choice keeps the record honest.
What a day holds
Each day carries one entry with several parts, all optional beyond the flow itself:
- Flow. One level per day: Not bleeding, Light, Medium, Heavy, or Super heavy. Spotting is its own tracked option, separate from flow — light staining between periods belongs there, which keeps period boundaries honest.
- Tracked options. Pains, feelings, sleep, and other signals, each its own record on the day, each with its own detail where it fits. Logging a few consistently matters more than logging many occasionally.
- Tags. Quick labels that make patterns easy to spot later. A day can carry several; the Custom tags list grows with the household's own words, searchable from the day sheet.
- A note. Note is free text — anything a label cannot hold.
The note has one privacy choice, made when it is written: marking it private keeps it hers alone. Guardians on the profile see that a private note exists — the day shows Private note — but not what it says.
Editing and deleting
Editing or deleting an entry
Any day can be changed or removed. Deleting keeps the day’s place but clears what it carried.
Opening a logged day lets you change its flow, options, or note. Saving overwrites that day only — nothing else in history moves.
Deleting an entry clears its content while keeping its place in the record, so a removed day never silently shifts the days around it. Deleted content syncs as deleted to every device.
Fixing a mis-logged day sooner keeps estimates sharper, but there is no deadline — history can be corrected at any time.

To change a day, open it, adjust anything, and Save — saving overwrites that day only. To remove a day's content, Delete from the same place; after confirming Delete this entry?, the day keeps its place in the calendar with nothing logged on it, and a snackbar offers Undo for a moment in case the tap was a mistake.
There is no deadline on corrections: a mis-logged day can be fixed at any time, and estimates recompute from the corrected history.
What happens to a logged day
Everything works offline; entries sync to the account's other devices the next time the device is online and signed in. When two guardians log on the same day at once, the entries merge rather than one overwriting the other — tags combine, and each field keeps the newest write.
